Electrical Engineering

Plot the signal s(t) = cos(2πt), and then illustrate theresulting samples with the following sampling intervals: [30points] •

Ts= 0.5 sec. •

Ts= 0.75 sec •

Ts =1 sec.

(a) For each case, also sketch the reconstructed continuous timesignal from the samples using linear interpolation (i.e. connectingsamples by straight lines).

(b) In which case the sampled signal has aliasing distortion?What is the minimal sampling frequency and the correspondingsampling interval needed to avoid aliasing?
